/* EQUALIZED KEMAR HRIR

How to generate these data:

1. You need the MIT Media Lab's KEMAR data, read it into an software
   capable of signal/time series analysis (like Mathematica, Matlab,
   ...)

2. Construct an equalizing FIR inverse filter by calculating the
   transfer function of the front, same side impulse response, then
   take 1 over the absolute magnitude.

3. Cut the poles in the inverse filter's transfer function
   specification by limiting the amplification to 2.5 (note, this
   number assumes that you have correct signal processing
   normalization of the Fourier transform).

4. Design the FIR inverse filter by calculating the inverse Fourier
   transform, then chopping the coefficients down to a reasonable
   number (N = 15 is used here), apply the Kaiser-Bessel window (alpha
   = 2 is used here).  Note the objective is remove the color bias
   only (as if you are using an equalizer), _not_ to do a full inverse
   filtering. (Note: beta = pi*alpha in other notation.)

   For N = 15, alpha = 2, you should get the following impulse
   response:

    0.001001558668605168,  0.00698457265741865,  0.040453643039829436,

   -0.30297563073747436,   1.3140211791355982,  -0.30297563073747436,

5. Linearly convolve all KEMAR HRIR with this inverse filter.

6. Resample from 44.1 kHz sampling frequency to 48 kHz.
